  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
2         large         egg whites
1         Cup           sugar
1/4       Cup           water
1         Teaspoon      light corn syrup
1/4       Teaspoon      cream of tartar 
1         Teaspoon      vanilla

Preparation:

With hand mixer, beat egg whites until foamy in the top of a double boiler, set about 2" from the simmering water. Beat in remaining ingredients and continue beating for about seven minutes (hence the name) or until temperature on a candy thermometer reaches 160° F and soft peaks form. Remove top of double boiler and continue to beat until stiff peaks form, about 4-5 minutes. Makes about 3 Cups (enough for 8" double layer cake)
